| Summary: | 碩士 === 國立中山大學 === 光電工程學系研究所 === 103 === Due to the low cost and ease of fabrication, organic semiconductors are promisingly novel materials for applications of large-area and flexible devices. The carrier transport capability of organic materials usually inferior to it of inorganic materials, but the versatile property of organic materials still makes organic optoelectronics as an emerging technology.
To be further competitive with inorganic materials, the carrier transport properties of organic materials need to be enhanced. The method to enhance the carrier transport capability of materials can be achieved by either molecule design strategy or molecule alignment. In this thesis, we investigate the relationship of carrier mobility and the structure of molecules through time-of-flight measurement. Also, we study the phase behavior of two liquid crystalline semiconductors. The carrier mobilities of the two liquid crystalline semiconductors with ordered molecule arrangement are discussed. The results show that the carrier mobility strongly depends on the stereostructure of the molecules and the effect of molecule alignment is not negligible.
